Hello!
I need a raid controller for FBSD 6.2 which has the following options
1) Full SATA-II support
2) Good rperfomance (over 50MB read, over 30 write) in mirror mode
3) No weird problems with freebSD (like with SRCS16)
4) Utility to monitor status of raids (command line or web)
5) Utility to rebuild, repair, manager arrays in OS
6) Preferably Intel
I'm very happy with ARECA ARC1110.
ARECA also provide cli tool for freebsd on their site.
I'm using it in RAID 10 configuration and here are few benchmark results
that I run on production server ;)

I know, 3ware has such good stuff, but those controller are not
certified for internet services in here (russia). So, i am pretty much
limited to Intel controllers. Is there intel controller which satisfied
all the
1-6 conditions? I only need mirroring.

I'll second Stefan with the Areca. I have an Areca 1120 8 port SATA2
controller.
It hasn't given me an ounce of issues. It's got a nice CLI and web based
interface as well as being SNMP manageable.
Been running mine for 2 years without any issues at all. It also supports
nifty things like online volume expansion and hot-swapping (if you have the
hot-swap SATA drive bays)
